Effect test

example 1

[0110]There were prepared a solution (a) by dissolving 76.6 g of sodium stearate in 3000 g of water maintained at 90° C. and a solution (b) by dissolving 40.3 g of silver nitrate in 600 g of water. Next, the solution (b) was thrown into the solution (a) while stirring the solution (a). After having stirred for 15 minutes from the throwing, washing was conducted to a sufficient degree by using deionized water while effecting the solid-liquid separation by filtration by means of suction. By using a hot-air drier (SPH-101 manufactured by Tabai-Espec Co.), the obtained solid was dried at 100° C. for 24 hours to obtain a silver stearate having a water content of 80 ppm. Next, by using the silver stearate, a film was prepared containing the ultrafine metal particles. The obtained film was subjected to the above deodorizing test to calculate the deodorizing ratio.

example 2

[0111]A silver stearate was prepared in the same manner as in Example 1 but conducting the hot-air drying at 100° C. for 20 hours so that the water content was 125 ppm. A film containing ultrafine metal particles was prepared and was subjected to the deodorizing test to calculate the deodorizing ratio.

example 3

[0112]A silver stearate was prepared in the same manner as in Example 1 but conducting the hot-air drying at 100° C. for 18 hours so that the water content was 184 ppm. A film containing ultrafine metal particles was prepared and was subjected to the deodorizing test to calculate the deodorizing ratio.

Abstract

A fatty acid metal salt used for forming ultrafine metal particles satisfying at least one of that:
(i) the water content is 200 ppm or less;
(ii) the volume-cumulative particle diameter D90 is 80 μm or smaller as measured by the particle size distribution measuring method of the laser diffraction/scattering type; or
(iii) a metal of an atomic weight of 50 to 200 is contained, and the amount of the unreacted substance or the by-product is 4.0 mol % or less when the fatty acid metal salt is formed. The fatty acid metal salt can be favorably used for forming ultrafine metal particles in a resin, or for forming a resin composition, a coating, a dispersion solution or a molded article containing the ultrafine metal particles.

Description

TECHNICAL FIELD[0001]This invention relates to a fatty acid metal salt. More specifically, the invention relates to a fatty acid metal salt that can be favorably used as a precursor for forming ultrafine metal particles, a resin composition containing the ultrafine metal particles, a coating containing the ultrafine metal particles or a dispersion solution of the ultrafine metal particles.BACKGROUND ART[0002]Fatty acid metal salts have heretofore been widely used in many fields such as in the field of electronic printing, in the field of powder metallurgy, in the field of cosmetics, in the field of coating materials, in the field of resin working and so on. For example, magnesium salts and calcium salts of fatty acid have been used for improving luster of the skin and adhesiveness in the field of cosmetics and for improving dispersion of pigments in the field of resin working.[0003]On the other hand, a silver salt of fatty acid has been used as a material for thermally developing an...
